1. An air quality sensor system, comprising:
a housing defining a sidewall means;
an internal secondary wall located within said housing;
an air input located on a first sidewall of said sidewall means connected to an air input tunnel extending to said internal secondary wall;
an air output located on a second sidewall of said sidewall means angularly disposed relative to said first sidewall of said sidewall means;
an air output tunnel connecting said internal secondary wall and said air output;
said air output having a cross-sectional area greater than a cross-sectional area of said air input tunnel to ensure a continuous and directed air flow from said air input to be exhausted from said air output; and
a particle counter including a fan located within said housing between said air input tunnel and said air output tunnel for sensing the number of particles passing between said air input and said air output.
